The system has an analysis unit (2) determining an analyte measured value for a body fluid specimen applied, and a fingerprint sensor unit (3) detecting fingerprint sensor signals for users. A control unit (1) is connected to the analysis unit and the fingerprint sensor unit for data transmission, where the control unit analyzes the detected fingerprint sensor signals and optionally additional detected fingerprint sensor signals in addition to a user identification to provide control signals for executing additional measurement system functions. An independent claim is also included for a method for operating a measurement system for analyte determination.
